forgotten and perhaps replaced

by 美儀

Pushing your glasses up the bridge of your nose when you’ve got contact lenses on.
Looking at your wrist when you’ve forgotten to put on your watch.
Ducking to avoid branches when you’re in a vehicle.

Something that has been around for a long time;

When it is gone–forgotten, broken, misplaced, replaced–at the beginning, it feels unusual or inconvenient; but with time, soon enough your mind adapts and forgets those previous reflexes and starts to depend on something new.

If it is easy to become familiar with something, and easy to be accustomed to its absence…could this condition apply to everything else?
